LOCK-COCK.

SPECIFICATION forming part of Letters Patent No. 664,462, dated December2 1 0 Application filed August 24, 1900. Serial No. 27,866. (No model.)

declare the following to be a full, clear, and

exact description of the invention,such as will enable others skilled inthe art to which it appertains to make and use the same, reference beinghad to the accompanying drawings, and to the letters of reference'markedthereon, forming part of this specification.

My invention relates to improvements in lock-cocks; and it consists,substantially, in constructing a plug-cock with slots on opposite sidesof the upper part of the cock-body and providing ajzollar having anopening therein adapted to pass over the rectangular end of the plugoperating therein and having downwardly-projecting lugs thereon adaptedto enter the slots on the cock-body, the upper end of the plug having anopening therein adapted to receive the hasp of a padlock, so as to holdthe logs on the collar in engagement'with the slots on thecock-body,whereby the cock can be locked either in a closed or openposition, as may be desired. These features of my invention arehereinafter fully set forth and described, and illustrated in theaccompanying drawings, in Which Figure l is a side view in elevation ofa plug-cock embodying my invention locked in an open position. Fig. 2 isa sectional view of the same on the line as a: in Fig. 1. Fig. 3

is a perspectiveview of the locking-collar of my device.

In the drawings, A is the body of the cock, andB the plug, operatingtherein in the usual manner.. In the upper part of the cock-body,

at each side of the larger end of the plug B, there are vertical slotsa, and through the rectangular end B of the plug B, I make an opening1), adapted to receive the hasp d of a padlock D. Upon the rectangularend B of the plug B, I place a collar E, upon which collar there aredownwardly-projecting lugs e 6, adapted to enter the slots at a in thecockbody. The opening 6 in the collar E, it will be observed, is made inthe form of a cross, so that whether the cock is open or closed thecollar E will pass down over the rectangular end B of the plug B, sothat the lugs e e thereon will enter the slots at a in the cock-body.Then by inserting the hasp d of a padlock in the opening bin the plugthe cock can be locked whether in an open or closed position, asdesired.

Having thus described my invention, so as to enable others to constructand use the same,

what I claim as new, and desire to secure by Letters Patent of theUnited States, is

In a lock-cock the combination of a cockbody A having vertical slots aon opposite sides of the upper part thereof, a plug operating in saidcock-body having a rectangular end B thereon and an openingbtherethrough, the collar E having a cross-shaped opening e adapted topass down over the rectangular portion of said plug, and lugs e e onsaid collar adapted to enter the small slots 0. a in the cock-body,substantially as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

JOSEPH B. CAMPBELL.
